 hi,
I am using electrical links to connect 4 piezoresistors to form a wheatstone
 bridge.I am applying voltage to 2 patches and i need to know output of the
 bridge.I am getting error message(unable to open output file) after
 simulation.Can anyone tell me how to connect 4 resistors and how to
specify voltages to complete the simulation.
 thanks
 manjula
Try this configuration:

 (1) Connnect a resistor of value R say R1 between node A  and B
 (2) Connecet another  resistor of value R say R2 between node B and ground.
 (3) Connnect a variable resistor of value X say Rx between node A  and C
 (4) Connecet another  resistor of value R say R4 between node C and ground
 (5) Connect your voltage source Vin between nodes A and ground.
(6) Measure output voltage Vout between nodes B and C.

      I hope this will clarify bridge measurement procedures. If you have
any questions contact me.
